Having trouble starting. If I put small amount fuel in throttle body cranks right up runs fine when turned off must repeat to start. Fuel pump good filters clean. My next guess would be fuel pressure regulater but im unsure

Test the fuel pressure with an accurate gauge. This engine requires a MINIMUM or 55-57PSI to start when cold. It should be over 60PSI.
